Figure 6.
Effects of inescapable footshock (IES) and a single injection of 40 mg/kg corticosterone (CS) on serum total corticosterone levels. The asterisk indicates that compared to nonstressed controls (NS), serum CS concentration is significantly higher 24 h following IES (Tukey test, p=0.008). The pound sign denotes that 24 h after injecting CS, serum CS concentration is significantly higher than those both in NS controls (p<0.001) and in animals exposed to IES (p<0.001). Seven days following treatments, there is no significant difference among serum CS concentrations (p>0.05).
